Abstract
The reaction of chromium aryl(alkoxy)carbenes with propargylic alcohols has
been investigated under dry state adsorption and ultrasound conditions. Wh
en compared to the corresponding thermal processes, the developed sonicatio
n reactions afford good yields of p-lactone products over generally shorter
reaction times. hy state adsorption affords diene products which are also
obtained from the corresponding p-lactones. (C) 1999 Elsevier Science Ltd.
